SOURCE: fuel pump relay location
the relay is located behind the glove box. You'll have to remove it, inside and all. Then you should see a pack of three relays just above the glove box opening. It will be the middle one. If not, please inquire to ToyotaED im sure he knows!

sorry never done one so i havent a clue,in the good old days the tach connected to the coil wire but now with all this fancy electrics ,Well what happens is they call it vehicle security so they dont have to release the diagrams and this is done to stop people like myself from by passing the immobilisers when we service a vehicle.Because no doubt as you are aware on new cars that if you drop the oil the immobiliser cuts in.Change the battery and the same thing happens.So what happens to keep the dealers in work ,yes you have guessed it no wiring diagrams ,multilayered circuit boards and wires all the same colour to stop people like me from soldering the two outside legs together of a big switching transistor together to make the vehicle general mechanic friendly.Also encrypted software is used to stop the fault codes from being read ,they throw up the wrong code ?? try asking dealer to install then post where he connected too .,best of british with it

The relay and fuse is located under the hood in the relay box. It will be labeled on the lid. If fuse is good, then test the relay. Pull it out and with a test light see if there is power. If there is then remember that one. Have some one turn the key on and find another power wire. There should be 2 powers.If there is only one power then there maybe a problem in the ignition switch. If there is 2 powers then you need to get to the top of the fuel tank and see if power is getting to the pump. The power at the pump will be there for only a few seconds once the key is turned on and then will drop off. Let us know how it goes.
